The AE-1000 is the dedicated 2-channel gap and crash controller from SBS. The AE-1000 reports initial contact between the grinding wheel and a new part to the machine control system, so that it can stop wheel in-feed without operator intervention. This can save up to 20% of the typical cycle time. It is simple to use, and features an OLED graphical display with universal icon-driven firmware.

It can also detect and report abnormal contact from an incorrectly loaded part of fixture within milliseconds (crash control), allowing the in-feed to be stopped, avoiding a crash, damage or injury.

Position control, used to zero the machine before a grinding or dressing cycle is possible by detecting the edge of the wheel touching a reference point known to the machine CNC. The CNC can therefore determine the exact position and diameter of a changing grinding wheel.

Monitoring for normal acoustic levels during wheel dressing permits the operator or CNC control to:

Determine if the wheel is being dressed fully across its width

Control the aggressiveness of the process

Maintain the quality of a dressed wheel to conserve wheel materials

The AE-1000 works with a variety of SBS acoustic sensors, all of which are easy to retrofit.
